TUBULAR .BELL

SPECIFICATION forming part of Letters Patent No. 686,301, dated. November 12, 1901.

Application filed June 12, 1901.

To all whom it may concern:

Be it known that I, CHARLES A. J AOQUES, a citizen of the United States, residing in the borough ofManhattan, city, county, and State of New York, have invented certain new and useful Improvements in Tubular Bells, of which the following is a specification.

My invention relates to tubular bells, and more particularly to the class of bells 'ernploycd in clocks.

I will describe a tubular bell embodying my invention and then point out the novel features thereof in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a clock-chime mechanism and showing supported from the framework comprised therein a tubular bell embodying my invention. Fig. 2 is a view, partly in elevation and partly in vertical section, of a tubular bell embodying my invention. Figs. 3 and 4 are side elevations of tubular bells, showing modified forms of my invention. Fig. 5 is a detail View of a portion of atubular bell, showing a still further modification. Figs. 2, 3, 4, and 5 are drawn to a larger scale than Fig. 1.

Similar letters of reference designate corresponding parts in all of the figures.

A represents one of a pair of uprights, each of which has a laterally-extending arm a, and a cross-bar A connecting them. This crossbar is provided with a number of projections a, from which are suspended, preferably by means of cords A tubular bells B.

A represents a support for a clock mechanism A which mechanism operates at intervals a pin-cylinder A which is adjacent said mechanism. The pin-cylinder A in its rotation moves on their pivots levers a supported on a cross-bar a An end of each lever is connected by a cord at with a hammer C, and the hammers C are supported by a cross-bar a It will be understood, of course, that a hammer and operating parts are provided for each bell B.

The bells B are, as stated, tubular--that is, the length of each bell is considerably greater than its diameter-but of that style of hell in which the metal of the tube is tuned to accord with the confined air-column; The bell B will, to have a confined air-column, be

closed at one of its ends and its wall will be without an opening from the cap end of the tube to the end of the air-column. The closiug of an end of the tube may be accomplished by means of a cap 1), which may be of any desired thickness. The tuning of the metal of the tube to bring it in accord with the confined air-column may be accomplished by cutting away a portion of the tube, as indicated at b in Fig. 3.

Instead of cutting the tube in the manner shown in Fig. 2 it may be notched, as indicated at b in Fig. 3, or split diametrically for a portion of the bells length, as indicated at b in Fig. 4. It may also be pierced with holes at one end thereof, as in a flute. The confined air-column extends from the closed end of the bell to the edge of the first cut or opening nearest the closed end of the bell. In all cases the material of the tube will be sonorous. Each bell will preferably be supported or suspended at or near the end of that portion of the tube confining the aircolumn, and preferably at a nodal point near the closed end of the tube. The advantage of supporting a bell of this style in this manner is that most of the weight is beneath the point of suspension and the swinging of the bell after being struck is materially lessened.

To preserve the air-column and yet suspend the bell by passing a cord through it, a tube 19 is passed through the bell and suitably secured in position. The opening between the wall of the bell and the wall of the tube is sealed. The suspension-cord A for each bell is passed through the tube Other ways of suspending a bell at or near its closed end maybe by means of laterally-exten ding hooks or lugs 19 or other projecting devices on the outside of the hell with which the suspension cord or cords engage. Instead the cap'b of each bell may be provided with a rib b pierced with an opening or openings through which the suspension cord or cords pass.

By using a tubular bell of this nature for clocks a much shorter bell can be used, thereby saving considerable space in the clockcasing.

What I claim as my invention is-- 1. A tubular bell, closed at one end to produce a confined air-column and having its metal tuned to accord with its confined aircolumn, and having means connected with the Wall of the tube inclosing the air-column and at or near the closed end of the tube Without destroying the confined aircolumn, by which the tube may be suspended in such manner as to have its weight beneath its point of suspension.

2. lhe combination With a tubular bell closed at one end to have a confined air column and having its metal tuned to accord with its confined air-column, of means passed through but not destroying the confined aircolumn, for permitting of a suspension of the tube.

3. The combination with a tubular bell closed at one end to have a confined aircolumn, of a suspension-tube passed through the wall of the tube and not destroying the confined air-column of the tubular bell at such a point as to have the Weight of the tube beneath the point of suspension.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

CHARLES A. JACQUES.
